I-silicon yepolycrystalline

I-silicon ye-Polycrystalline luhlobo lwe-silicon esisiseko.Xa i-silicon etyhidiweyo ye-elemental iqina ngaphantsi
iimeko zokupholisa okukhulu, iiathom ze-silicon zicwangciswe ngendlela ye-diamond lattice ukwenza ezininzi
iinuclei zekristale.Ukuba ezi nuclei zekristale zikhula zibe ziinkozo zekristale ezineziqhelaniso ezahlukeneyo zeplanethi yekristale, ezi
iinkozo zekristale zidibanisa ukwenza isilicon yepolycrystalline..Ixabiso lokusetyenziswa: Intsingiselo yophuhliso lwelanga
iiseli zinokubonwa kwinkqubo yophuhliso lwangoku lweeseli zelanga zamazwe ngamazwe.

I-silicon yepolycrystalline ingasetyenziswa njengezinto ezikrwada zokutsala isilicon enye yekristale.Umahluko phakathi
I-silicon ye-polycrystalline kunye ne-silicon eyodwa ye-crystal ibonakala ngokukodwa kwiipropati ezibonakalayo.Umzekelo,
i-anisotropy yeepropathi zoomatshini, iipropathi ze-optical kunye ne-thermal properties azicacanga kakhulu kunoko
leyo yesilicon eyodwa yekristale;ngokubhekiselele kwiipropati zombane, i-conductivity ye-silicon ye-polycrystalline
Ikristale nayo ayibalulekanga kangako kunaleyo yesilicon enye yekristale, kwaye iphantse yangabikho conductivity.
Ngokumalunga nomsebenzi wekhemikhali, umahluko phakathi kwezi zibini zincinci.Polycrystalline silicon kunye
I-silicon ye-monocrystalline inokwahlulwa ngokubonakala kwayo, kodwa ukuchongwa kwangempela kufuna
uhlalutyo ukumisela isalathiso se-crystal plane, uhlobo lwe-conductivity kunye ne-resistiveivity ye-crystal.
